These amplifiers work in “push-pull” configuration, triples load and autobias.
They can work with various types of penthodes: KT120, KT90, KT88, 6550, 6CA7 or EL34.
The function phase shifter is assured by a triode double ECC82 and the function driver by an ECC83. It can work in symmetric mode on option.The output transformers, guaranteed for life, allow an adaptation of impedance from 1 to 16 ohms.
The power transformer is oversized for a better dissipation of heat and vibrations.
The cathode circuit is protected by individual fuses.
The filtering of the high voltages is ensured by high capacity capacitors.
The tubes are heated by alternate current with balance and noise reduction.
Two output terminals allow bi-wiring.
Gold connections ensure a faithful broadcast of the signals.
These devices are assembled using “point to point” wiring with silver / copper solder.
The frame is made of non-magnetic stainless steel which protects the device from external disturbances.
Released in 2013, the new JA120 builds on Jadis’ tradition of combining fine hand craftsmanship with state-of-the-art innovation and design. The JA120 benefits from several important enhancements and raises the bar with no-compromise regarding audio performance.
